Summary
Heterotopic bicaval stenting is an alternative treatment for severe tricuspid regurgitation (TR). This report details two cases of diaphragmatic paralysis, a previously undocumented complication of this procedure.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Device Technology
Background:
- Severe symptomatic tricuspid regurgitation (TR) poses significant challenges, often requiring advanced interventions.
- Heterotopic bicaval stenting presents a novel therapeutic strategy for managing systemic effects of TR.
- Optimal medical therapy may be insufficient for certain TR patients.
Observation:
- Two patient cases undergoing heterotopic bicaval stenting were analyzed.
- Procedure-related complications were meticulously documented.
- Unilateral diaphragmatic paralysis was identified as a notable adverse event.
Findings:
- Heterotopic bicaval stenting, while offering therapeutic benefits, is associated with procedure-related unilateral diaphragmatic paralysis.
- This complication has not been previously reported in existing literature.
- The diaphragmatic paralysis was linked directly to the stenting procedure.
Implications:
- Clinicians should be aware of diaphragmatic paralysis as a potential complication of heterotopic bicaval stenting.
- Further research is warranted to understand the mechanism and incidence of this complication.
- This finding may influence patient selection and procedural techniques for bicaval stenting in TR management.
